ELEVATlNG-TRUCK.

SPECIFICATION forming part of Letters Patent No. 671,452, dated April 9,1901.

Application filed January 3, 1901. Serial No. 42,011I (No model.)

of Tennessee, have invented certain new and useful Improvements inElevating-Trucks, of which the following is a specification.

My invention relates to improvements in elevating-trucks more especiallyfor use in loading and unloading and transporting bricks from one placeto another.

The object of my invention is to provide a device which is simple andinexpensive in construction, easy to operate, and which will save theexpense of providing a multiplicity of trucks for supporting brickswhile being dried or to obviate the necessity of employing more than oneman to remove a pallet of bricks from the truck to a suitable rest andalso obviate the necessity of handling brick individually when it isdesired to transport them from one place to another.

Referring to the drawings, Figure 1 is a side view in elevation of myimproved elevatingtruck, shown in connection with a suitable track, anda frame, with a pallet or platform having bricks piled thereon; Fig. 2,a top plan view with the pallet or platform removed; Fig. 3, a frontelevation of the elevating-truck; Fig. 4, a horizontal section on theline a; a: of Fig. 1; Fig. 5, a vertical section on line 3 y of Fig. 1;Fig. 6, a detail view.

In the drawings, in which like letters of reference denote like partsthroughout the several views, A represents a track, and B a frame, bothof which may be of any desired length. 0 is a pallet or platform adaptedto rest on the top of said frame, made preferably slatted, and D is apile of bricks thereon.

E is the elevating-truck, which is provided with suitable axles F,having wheels G, posts H and I, with vertical V-shaped grooves J,stationary side bars K, and vertically-movable side bars L, havingpointed ends M, which engage and slide in the grooves J of the posts Hand I.

N represents two sets or pairs of toggle- 'jointsone set on each side ofthe truckthe upper and lower ends of which are pivoted to theverticallymovable and stationary side -to brace the same.

bars, respectively. Rods 0 connect each set of toggle-joints.

Each of the posts H is provided with vertical slots P, and Q, is ahand-lever, the ends of which are pivoted atR in the slots P. Thehand-lever and bars 0 are connected by links S, one end of each of saidlinks being pivoted to the hand-lever at T and the opposite end to oneof the bars 0 at U. A crossbar is connected to the top of the posts Hand serves The posts I may be braced in a similar manner.

The frame B may be continuous, or it may consist of two or moreframessay, for instance, one frame may be situated at the place wherethe truck receives the load and another at the place it is desired tounload the same to receive the load from the truck.

Although I have described my invention as particularly applicable toloading, unloading, and transporting bricks from one point to another ona suitable frame, or from one frame to another where more than one frameis used, it may be used equally as well to load and unload otherarticles-such, for instance, as trunks, boxes, barrels, blocks ofmarble,

&c.--and lighten the labor of those engaged in such work, or it may beused, by means of its leverage, to elevate a load to the height of adray-bed or a car-door or any such elevation where it may be founddesirable to unload from the truck.

The operation is as follows: The pallet or platform is first placed onthe top of the frame, the bricks to be transported piledupon the same.The truck is moved along the track until it is immediately under thepallet. Then by lowering the hand-lever the rods 0 will operate thetoggle-joints, and they in turn will raise the movable side bars upwarduntil they contact with the bottom of the pallet and elevate the sameabove the frame B. The truck is then moved along the track until thepoint is reached where it is desired to unload the bricks. Then thehandle is raised, thereby operating the rods 0 and toggle-joints andlowering the movable side bars until the pallet with the bricks againrests on the top of the frame B.

Having thus described my invention, what I claim isl. A transportingdevice comprising a truck having a frame provided with slots, movableside bars, a lever pivoted in said slots adapted to operate the sidebars, and means for connecting the side bars to the lever, substantiallyas shown and described.

2. A transporting device com prising a truck having stationary andmovable side bars, toggle-joints connecting the same, posts havingslots, a lever pivoted in said slots, and means for connecting the leverwith the togglejoints, substantially as shown and described. 1
